Avril Lavigne and husband Chad Kroeger have been hounded by divorce rumors but over the weekend, they proved that their marriage is still quite strong when they were snapped hand-in-hand on the beach in Miami, Florida.

The "Let me Go" singer wore a strapless maxi-dress and Ugg boots. She shielded her face with a cowboy hat and sunglasses.

"It's clear that the couple are still very much going strong, after they were hit with rumors of an imminent divorce in the autumn of last year, said Daily Mail. "Avril posted a photo to Instagram which showed her and Chad sticking their tongues out on Monday as they prepared to head home from their getaway."

Avril Lavigne admitted to being sick with Lyme disease amid the divorce rumors surrounding her marriage to Nickelback frontman Chad Kroeger. The "Complicated" singer then asked her fans for prayers for her recovery.

Avril Lavigne wrote on AvrilMusicChart to send a message to her fans.

"I feel bad because I haven't been able to say anything to the fans to let them no why I've been absent," she said. "I'm not feeling well. I'm having some health issues. So please keep me in your prayers. (sic)"

In December last year, Chad Kroeger addressed divorce rumors with Avril Lavigne in an interview with Entertainment Online Canada.

"You know my dad calls me up and he's just like, 'I haven't slept in 2 days, what's going on?'" he said. "I'm like, 'Dad you're not buying all this crap are you?' You know, I get to hear all the rumour mill stuff. I find it very amusing."

"That's high school multiplied exponentially. It's ridiculous. How many times has Jennifer Aniston been pregnant this year? A dozen? Let's start a new rumor. I'm pregnant," he quipped, talking about the Hollywood rumor mill that could spiral out of control.
